Trait StrictRInt 

#[doc(hidden)]
pub trait StrictRInt: Copy + Display {
    const NAME: &'static str;

    // Required methods
    fn to_r_int(self) -> Option<i32>;
    fn range_reason(self) -> String;
}

A lossy integer type for the strict outbound path: its R integer, if any, and the reason it has none.

Required Associated Constants

const NAME: &'static str

The Rust type name the panic message uses.

Required Methods

fn to_r_int(self) -> Option<i32>

Some when the value is an R integer: it fits i32 and is not i32::MIN, which is NA_integer_ in R.

fn range_reason(self) -> String

Why self has no R integer.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
